On.The crucible lid that seal groove 4 and cooperation are equipped on the outside of the upper ends crucible A is melted, seal groove 4 is the annular seal pocket that section is U-shaped.High alumina
Al in ceramic material composition2O3Ingredient >=70%, and SiO2≤10%.It melts crucible A to be mounted in independent melting furnace 1, charge door position
In top outside 1 stove of melting furnace, the communicating pipe melted crucible A and aoxidized between crucible B is designed using dock is inserted into, and in docking section
Set up separately and sets water flowing ring 5 and heating electrode retaining collar 6.It is mounted on blender 10 in homogenizing crucible C and work crucible F, and the two crucible body is adopted
It is designed with bottle-neck, crucible body bottleneck and 10 spacing of blender≤2cm, the metal level in work crucible F is in bottleneck.
Using Al2O3Ingredient >=70%, and SiO2The fusing crucible of fluorine phosphorous glass continuous induction melting furnace described in≤10% ceramic material
A, and be installed in independent melting furnace 1.Using platinum material make the fluorine phosphorous glass continuous induction melting furnace oxidation crucible B,
Change crucible C, clarifying basin D, cooling crucible E and work crucible F, each section all uses Elema or Si-Mo rod to carry out radiant type heating.
Air inlet pipe is installed on oxidation crucible B, homogenizing crucible C, clarifying basin D, cooling crucible E, the first snorkel 8 of crucible B will be aoxidized
Nozzle is arranged in metal level hereinafter, the second to the 4th snorkel 15-17 nozzles of homogenizing crucible C, clarifying basin D, cooling crucible E are set
It sets more than metal level.
First blender 10 is mounted on homogenizing crucible C and the blender for the upper ends crucible F that work, then carries out the two crucible body top
Welding, crucible body bottleneck and 10 spacing of blender≤2cm.
Smelting furnace can oven after the completion of building by laying.Fluorine phosphorus P series glass fusion temperature is relatively low (≤850 DEG C), is closed passing through
The temperature at seal groove 4 can be made to be less than 100 DEG C after the heat-insulated and crucible body drop design of reason, therefore can be injected into seal groove
Water is as sealing fluid, the opposing seal of crucible when realizing charging interval.
Occur bursting phenomenon to melt crucible A in order to prevent, be needed before use in advance by 1 slow preheated oven of melting furnace, in temperature
When degree is up to 500 DEG C or more, oven heating rate need to be controlled in+25 DEG C/h or less.Because strictly controlling smelting furnace temperature rate,
And smelting furnace is always for the condition of high temperature, so fusing crucible A is not in burst phenomenon.
A kind of melting method using glass continuous induction melting furnace of the invention, includes the following steps：
1. fusing crucible A is docked with oxidation crucible B, and continue water flowing into water flowing ring 5 to ensure interface coolant seal；
2. opening crucible lid 3 when continuous smelting starts to feed, the blender 10 opened homogenizing crucible C and worked in crucible F is surveyed by liquid level
Prospect hole 12 carries out level gauging and monitoring, passes through first to the respectively in oxidation crucible B, homogenizing crucible C, clarifying basin D, cooling crucible E
Four air inlet pipe 8,15-17 are passed through O2；
3. when glass powder obtains oxic gas after being fused into glass metal in melting crucible A by being introduced into oxidation crucible B communicating pipes 11
Atmosphere enters back into homogenizing crucible C and is stirred homogenizing, enters back into clarifying basin D de-bubbles, enters back into cooling crucible E and work crucible F slowly drops
Temperature；
4. leaking injection forming finally by material leakage pipe 14, the continuous smelting production of fluorine phosphorous glass is realized.
By contrast test we have found that：In such ceramic material, work as Al2When the content of O increases, corrosion resistance meeting
Gradually improve, and with SiO2Its corrosion resistance of the increase of content is then gradually deteriorated, specifically as Al in ceramic material composition2O3
Ingredient >=70%, and SiO2The purpose of the anti-fluorine phosphorous glass powder erosion of the present invention can be preferably realized when≤10%.

It is docked to fusing crucible A with oxidation crucible B when beginning, continues water flowing into water flowing ring 5, continue, to fusing crucible A Inner chargings, to open homogenizing
Blender 10 in crucible C and work crucible F goes out when the metal level in homogenizing crucible C and the crucible F that works is in bottleneck and starts material leakage
Stove.Start after coming out of the stove, rationally control charging and material leakage speed make metal level height stablize relatively.In normal smelting, Xiang Tong
Water ring 5 continues water flowing, when needing to remove replacement melting furnace, stops water flowing and simultaneously opens heating electrode retaining collar 6.
Level gauging and monitoring are carried out by liquid level instrument connection 12, in oxidation crucible B, homogenizing crucible C, clarifying basin D, cooling crucible E
O is inside passed through by first to fourth air inlet pipe 8,15-17 respectively2.When powder will lead to after being fused into glass metal in melting crucible A
It crosses and is introduced into oxidation crucible B acquisition oxidizing atmospheres communicating pipe 11, enter back into homogenizing crucible C and be stirred homogenizing, enter back into clarifying basin D and remove
Bubble, enters back into cooling crucible E and work crucible F slow coolings, leaks injection forming finally by material leakage pipe 14, realizes the continuous of fluorine phosphorous glass
Melting produces.
Because usually containing Al in fluorine phosphorous glass formula3+Equal cations, so the present invention uses the ceramic material system of high alumina
Making the advantage of fusing crucible is：While effectively preventing platinum particle and fusing into glass, the cation of inside glass is matched
It will not produce bigger effect, the reasonable increase and decrease of corresponding ingredient need to be only carried out when glass raw material is prepared.
